But Spirit Run: Fire vs. Ice, a new endless runner from developer Lunagames, made me question all of that. Suddenly, I was transforming when I wanted to jump, and jumping when I wanted to slide, and just falling the hell off of things that I normally wouldn’t.

That isn’t to say that it’s a bad game; it’s actually quite good. But be prepared to feel like a monkey trying to do algebra. You know, if that’s a thing that one might call upon monkeys to do.
